And copy these lines back into the original background -
__ __ __ __
.===|__| .===|__| .===|__| .===|__|
|| || || ||
|| || || ||
|| || || ||
6 || || || ||
A+7 [] _ _ [] _ _ [] _ _ []_ _
[] [] [] []
[] [] [] []
And the next line -
A+7 [] _ _ [] _ _ [] _ _ []_ _
B __// |___. __// |___. __// |___. __// |___.
8 [] [] [] []
Now we have a situation where the foreground characters are on top of
the background characters, so we simply delete any covered background
letters and replace them with the foreground ones -
A+7 [] _ _ [] _ _ [] _ _ []_ _
B __// |___. __// |___. __// |___. __// |___.
B+8 [] __// |___. [] __// |___. [__// |___. __// |___.
8 [] [] [] []
Putting the wanted lines back into the background -
__ __ __ __
.===|__| .===|__| .===|__| .===|__|
|| || || ||
|| || || ||
|| || || ||
|| || || ||
A+7 [] _ _ [] _ _ [] _ _ []_ _
B+8 [] __// |___. [] __// |___. [__// |___. __// |___.
[] [] [] []
And so on until -
__ __ __ __
.===|__| .===|__| .===|__| .===|__|
|| || || ||
|| || || ||
|| || || ||
|| || || ||
A+7 [] _ _ [] _ _ [] _ _ []_ _
B+8 [] __// |___. [] __// |___. [__// |___. __// |___.

One multi-layer continuous stereogram! Phew!
Yes this technique is a bit laborious, but you'll find that you make
fewer mistakes when copying layers on top of each other. If you want more
layers, you simply overlap them as shown.

6. To mask or mix
'The Phantom of The Opera is here...'. Well, almost the right type of
mask, but no star prize. Masking is a technique I sometimes use when I'm
working on complicated stereograms.
The 3D effect relies on the brain being able to overlap two images to
form a three dimensional one. Well sometimes, layers overlap in such a
way to leave only one image. Let's take a look at the bottom of the jeep
drawing again -
|| || || ||
[] _ _ [] _ _ [] _ _ []_ _
[] __// |___. [] __// |___. [__// |___. __// |___.
[] |'_ '--' _ | []|'_ '--' _ | |'_ '--' _ | |'_ '--' _ |

Notice that the street light is obscured here. Looked at in 3D, this
part of the street light is now difficult to see properly as it has
nothing to overlap with.
The simplest way to cure this problem is to shift the jeeps one column
to the left to obscure the street light. However, this is difficult in an
overlapped drawing and it just causes new problems with other clashing
layers.
Instead, the next best thing to do is try to mask off the offending
characters. By this I mean draw an imaginary blank layer around the fore-
ground image - in this case, the jeep. This gives you -
|| || || ||
[] _ _ [] _ _ [ _ _ _ _
[] __// |___. [] __// |___. __// |___. __// |___.
[] |'_ '--' _ | []|'_ '--' _ | |'_ '--' _ | |'_ '--' _ |
`(_)----(_)'= `(_)----(_)'= `(_)----(_)'= `(_)----(_)'=
Now this is not the best example as I've deleted a lot of characters,
but it does illustrate the how the picture can be 'cleaned up' by trying
to remove characters that don't appear to fit properly. This is very much
personal judgement, particularly since once you start to draw more
complicated drawings with three or four complicated layers, you will get
character clashes that *cannot* be removed with masks, no matter how hard
you try!
Still here? You are keen, aren't you?!! ;-)
Well this concludes the sections on the basic drawing techniques, the
next section lists some of the common problems that arise when drawing

If you're new to viewing 3D art, you may find that images over 15 - 18
columns are too wide. This is because your eye muscles will need time to
strengthen and your brain will need time to learn ...
